Hi Kieran, I've spent a fun Sunday playing around with this... thanks for the challenge! Jumping in to post it though, I think my ideas overlap with Siriuskey and Lucia. Isn't it funny how similar solutions can be arrived at independently! Key points: - As far as possible, I've tried to stick with the existing walls. - Since Bed 2 & Bed 3 are quite small already, even though I've encroached into each to achieve separate entries, the impact is minimal, particularly for Bed 3. - I've used pocket doors to both ends of the WIR and to the store room for optimal functionality. - I've depicted Caroma Urbane compact toilet suites with wall concealed cisterns because they save a bit of space and both toilets can use that extra space in that direction. - It's a very stageable design. You may for instance decide to build the ensuite/WIR and reconfigure the bed 2/3 entries without doing any of the kitchen changes. Or you may decide to save the expense and not move the main WC into the existing store, though it does add a fair area to the living space (I've used the exact existing footprint of the store to save cost and demolition pain which is workable with the Caroma Urbane, but alternatively you could demolish and rebuild the wall behind the pan for a more spacious loo). - The Family/Dining area ends up being fairly generous and very flexible. I've added a door to the end of the corridor to screen the loo a bit better from the dining area and for noise separation for the study, but you may prefer to leave this off. - I've not mucked around with your windows, figuring the important thing was to get the concept down for you, except in the ensuite. Really good idea there to have a central mirror with a narrow window to each side to throw light on your face at the mirror. Has the side benefit of a symmetrical effect which is always good aesthetically. - I've also flipped the main bathroom door to relate better to Bed 2/Bed 3, though not strictly necessary. - I originally used the Bed 1 robe space as a big walk-in-pantry, but it didn't relate particularly well to the kitchen and it also left no provision for general storage. Rather than take up a lot of valuable kitchen space with a pantry which would reduce the length of the peninsula breakfast bar (not ideal), I came up with the idea of shallow shelves with a roller shutter which I think you'll find give you an amazing amount of readily accessible storage. I'd like to think it would be possible to source a horizonal roller shutter that would coil back into the dead space at the back of the fridge, but perhaps better to just go with a vertical shutter and avoid the headache!

I'm no expert but just my thoughts if it was my house - The bedrooms are on the small side, so perhaps think about how they will be used - do your children need space to play or do homework in their rooms? Is the 4th bedroom for guests or will it be used as a home office? In bedrooms 2 and 3 the beds are below the window - are the windows high enough to allow a bedhead/to not lay down with your head against the window? What will be in the main bathroom - shower, bath, single/double vanity? What are you thinking layout wise? I'm confused by the kitchen, especially the pantry access given the corners are blocked by other benches - is it meant to be a walk in pantry or just normal cupboards? The hall is long and narrow and you need to go past all the bedrooms before you get to the living space. Not sure how well this will work, but I've only lived in places where the entry is adjacent to living space. Love the idea of having a separate self contained space for your parents - as others have said bathroom is too far from either bedroom, and the entry near bedroom could be an issue.

as long as the bench etc in the entry is low and shallow there should be enough space in the entry and wiw although Kate's idea of stealing space off the generous bedroom would allow for more .. my suggestions also includes tall 150mm deep shallow shelves in the wip (partly recessed into the wall) provides storage for cans, bottles and packets and avoid the corner cupboards in the narrow space and i've included some ideas for the kitchen

i've used dreamers idea for the laundry door and extra light and ventilation can be added to internal bathrooms with Solar skylights and ducted exhausts and my other suggestions loses the extra corner in the guest room to allow for a bigger bed 4, bigger study with BIW, bigger rumpus and living area, better staircase with smaller western window and void, separation of kids bedrooms from rumpus room, more comfortable master ens and wiw, family bathroom designed for sharing with chute to laundry, both powder rooms have handbasins and there's an upstairs WIL and optional space for a kitchenette.. the alcove in the dining room makes an ideal location for cellar, wine or coffee bar, there's generous storage throughout and suggest adding windows to every external room to improve ventilation and external shutters will help minimise overheating...
